14.31  The StatisticalChopper_Monitor McStas Component

Monitor designed to compute the autocorrelation signal for the Statistical Chopper

Identification

• Author: C. Monzat/E. Farhi

• Origin: ILL

• Date: 2009

Description

This component is a time sensitive monitor which calculates the cross correlation between the pseudo random sequence of a statistical chopper and the signal received. It mainly uses fonctions of component Monitor_nD. It is possible to use the various options of the Monitor_nD but the user MUST NOT specify "time" in the options. Auto detection of the time limits is possible if the user chooses tmin=>tmax.

Input parameters

Parameters in boldface are required; the others are optional.
